iPhone Footage Glitching Out

Machine is a 2017 13" MBP. What version of macOS and what version of FCPX? What codec, H264 or HEVC? In general I'm a little leery of shooting and editing HEVC.
Does this only happen with certain effects? What if you duplicate the project via right-click, duplicate as snapshot. Then load that duplicate project, select all clips in the timeline via CMD+A, then strip out all effects via Edit>Remove Effects. Export that. Does the problem ever happen? If so it may be a 3rd party effect, maybe one which is not compatible with the version of macOS or FCPX you are running.
Does it ever happen if you play the camera clip in Finder before importing it? You can try transcoding the material within FCPX via creating optimized media.
In case it's hardware you can try running Apple Diagnostics. If this finds no problems that's not a "clean bill of health" since the test is very basic, but it's easy to run: support.apple.com/en-us/HT202731
